Comment on 'mass accommodation coefficient of water: Molecular dynamics simulation and revised analysis of droplet train/flow reactor experiment'

Aerodyne Research Inc./Boston College (ARI/BC) group's studies showed that the accommodation coefficient (alpha) for H2O(g) entering liquid water has a negative temperature dependence, with the magnitude ranging from 0.17 plus minus 0.03 at 280 K to 0.32 plus minus 0.04 at 258 K. The experiment suggest that the ARI/BC measurements of alpha for H2O(g) entering liquid water obtained with the droplet apparatus are consistent with a value of alpha=1.
